RAIL-SECURING MEANS.

Application filed June 1, 1925.

This invention relates to improvements in metal railway ties and to the means for fastening the rails thereto.

In my Patent No. 1,512,458, reissued as No. 16,023 on March 17, 1925, I have disclosed and claimed retainer bars welded to the tie on both sides of the rail, and in my Patent No. 1,516,085, I have disclosed and claimed retainer bars bolted to the tie on both sides of the rail, the tie being of a special section to cooperate with the hook-shaped heads of the bolts, certain of the bars in each case being recessed to overlap the adjacent edge of the rail flange.

In the present instance, I make use of the welded bar on the outside of the rail, and the bolted bar on the inside of the rail, the tie being of the same section as in Patent No. 1,516,085. While I have shown the tie as provided with stabilizing means at its ends to preventits moving vertically in the ba1- last or tipping before the latter is thoroughly tamped, such means is immaterial to the present invention and forms the subject matter of a divisional application.

It will be understood that, with a metal tie of this, or other suitable section, it is very important to avoid any punching or cutting of the tie under or near the rail, because the continual pounding at this point of greatest stress will eventually break the tie, if there is any place for the fracture to start. But the weight of the tie must be kept down in order to reduce its cost. This necessitates thin sections, which are subject to crystallization and breakage from the pounding of the wheels. Hence my special T-section to avoid the use of bolt holes and the like. By welding the bars to the ties on the outside of the rails, spreading of the latter is positively prevented, which might occur, if bolted bars were used on the outside, by the bolts shaking loose due to vibration. There is no such lateral stress on the inside retainer bars, which can therefore be conveniently bolted on, so as to be removable and adjustable to take up wear. Furthermore it is only necessary to provide the inside bars with overlapping portions to hold the rails from lifting from the ties, so that I prefer to construct the welded bars without overlapping portions, which not only facilitates the removal of the rails, but also permits of adjusting them laterally when their heads become worn, as on curves; this is done by moving the rail laterally towards the inside,

after correspondil'lgly adjusting the bolted bars, and insertin a special form of. shim between the rail flange and the plane vertical face of the welded bar, as will be hereinafter fully described. It will. be understood that the welded bars may also have overlapping portions, if desired, and that the overlapping portions of either the inside or outside bars, or both, may stand at a greater angle to the horizontal than the top of the rail flange, as described in my aforesaid patents, or at substantially the same angle, as desired.

Another feature of novelty is aretainer plate for use when the rail has to be shimmed up from the tie.

The invention is illustrated in the aecompanying two sheets of drawing, in which,

Fig. 1 is a partial elevation of the top of a tie, with a rail foot in section secured by my improved means;

Fig. 2 is a similar View showing the shim used to adjust the rail where worn;

Fig. 3 is a View at right angles to Fig. 2, taken on line 33 of said figure;

Fig. 4 is an elevation of one end of a tie, with a rail in section, showing'the retainer plate used when the rail is raised by a wood shim;

Fig. 5 is a section on line 55 of Figure 4, and

Fig. 6 is a plan view of Figure 1 with the rail and wood shim removed.

In these views, the tie is shown as a rolled metal beam of T-section, comprising the web 1 and head 2, the edges'of the latter being provided on their lower sides with bulges 3. So far, it does not differ in any way from the tie disclosed and claimed in my Patent No. 1,516,085. ment of the tie in the ballast and to prevent its tipping before the latter is finally tamped around it, I provide each end of the tie with anchoring and stabilizing means, such as an angle plate 5, of the same width as the head of the tie and secured to the end of the latter as by welding or brazing.

The rails are shown at 9, with their flanges 11, by which they are secured to the heads of the ties, the securing means, in the present instance, comprising a bar 15, welded, or otherwise permanently secured, to the tie on the outside of the rail, as in my reissue Patent 16,230, aforesaid, and a bar 16, bolted to the tie on the inside of the rail, as in. my Patent 1,516,085 aforesaid. While both bars may be recessed to overlap the rail To prevent vertical movetill llange,it desired, I prefer to have the boltedon bar, only, so overlap, the welded-on bar presenting a plane vertical face to the adjacent edge 01 the rail flange. Said bar 16, shown as of rectangular section, may be L- shaped, if preferred. The overlapping portion of the bolted-on bar 16 may tit snugly over the rail flange edge, as shown 1n Figs.

2 and l, or may have its lower surface at a greaterangle to the horizontal than the top of the rail flange, as shown in Fig. 1, and as claimed in my aforesaid patents, to enable the rail to be removed by tilting it, without requiring the removal of the bolted-on bars. The plane vertical face of the welded-on bar enables me to provide means toradjusting the rail laterally to compensate for wear of its head on curves, as illustrated inFig. 2',

in which a tragi'nentary portion 12- of a car This shim, the thickness of which is, of

course, selected for the particular adjustment required, is secured in place by having its ends 17 bent down and around the bulged edges of the tie flange, as shown in Fig. 3.

The bolted-on bar 16, as shown, is similar to that of my said Patent1,516,085 and needs no detailed description here. Naturally it may be modified in construction somewhat without departing from the present invention, as presented in the appended claims.

here, as in the present instance, the ties are held rigidly in the ballast, it is sometimes necessary in winter, when frost 'heaves one end of a tie above the'other, to raise one of the rails by interposing a wood shim between it and the tie. This may raisethe rail to such anextent that the welded-on retainer bar is no longer eii'ective to hold the rail in place, because the edge of the rail flange is now above the top of said bar, I have there-' fore devised the retainer plate 18, shown in Fi l. 5 and 6. This plate,of sheet metal, is,

ot the width of the tie head and is interposed between the latter and the wood shim 19. The outside edgevof the plate is cut out to {providelugs 21, extending past the ends of the welded bar .15, and the inside edges ol said lugs are bent upwardly to form abutments 22, of greater height than the bar 15, and abutting the edge of the rail flange, as appears in said views. It will. be understood that the term welding or welded, used above and in certain claims, includes equivalent methods of fastening, such as brazing.

What I claim is I 1. The combination with a metal tie 01' T section, having, the underside of the outer edges of its head provided with longitudinal bulges, an abutment permanently secured to the head of the tie to prevent outward movement of the rail, a clamp bar constructed to overlap the inside flange of the rail, and bolts to hold said bar to the tie, the heads oi said bolts being hook-shaped to engage under said bulges, whereby no holes or cuts in the tie are required and the rail can be adjusted laterally to compensateior wear on its head by ioving said bar longitudinally of the tie and interposing a shim between the rail and said abutment.

The con'lbination with a metal tie oi? T- section, of abar adapted to be permanently secured to the tie so as to present a plane vertical'i'ace to the outer edge of the rail flange, a shim adapted to be interposed be tween said face and said edge with its ends bent down around the edges of the tie head, another baradaptedto be adjustably and removably secured to the tie so as to overlap the inner, edge of the rail'iiange, and bolts, engaging iunder thehead of the tie, to hold said last mentioned bar in adjusted position, whereby no holes or cuts in the tie are required.

3. The combination with a metal tie, of a bar welded thereto on the outside of the rail so as to present a plane vertical face to the edge of the rail flange, adjustable and rcmovable clamps overlapping the flange on the inside, and a retainer plate for use when the rail is raised from the tie by the interposition of a woody shim or thelike, said retainer plate having its outside edge out out to fit around the ends of said bar, and having portions bent up'at the sides adjacent said ends and extending above said bar to prevent spreading of the rails.

In testimony whereof I have hereunto set my hand;
